Gushonga ibipimo byerekana ubukana bwa polyethylene buke bushingiye kuburemere bwa molekile hamwe nibiranga amashami

Agaciro MFI kavuzwe kuri datasheets nyinshi kerekana umubare wa polymer usohoka binyuze muri orifice izwi (gupfa) kandi ugaragazwa nkubwinshi muri g / 10 min cyangwa kuri Melt Volume Rate muri cm3 / 10mins.

polyethylene nkeya (LDPE) irangwa hashingiwe ku gipimo cya Melt Flow Index (MFI).MFI ya LDPE ifitanye isano n'uburemere bwacyo bwa molekile (Mw).Incamake yubushakashatsi bwikitegererezo kuri reaktori ya LDPE iboneka mubitabo byeruye byerekana itandukaniro rikomeye mubashakashatsi kubijyanye na MFI-Mw, kubwibyo rero hagomba gukorwa ubushakashatsi bwo gutanga isano ryizewe.Ubu bushakashatsi bukusanya amakuru atandukanye yubushakashatsi ninganda mubyiciro bitandukanye bya LDPE.Isano rifatika hagati ya MFI na Mw ryatejwe imbere kandi isesengura ku isano ya MFI na Mw rirakemurwa.Ijanisha ryamakosa hagati yicyitegererezo nicyitegererezo cyinganda ziratandukanye kuva 0.1% kugeza kuri 2,4% bishobora gufatwa nkibisanzwe.Icyitegererezo kidafite umurongo cyabonetse cyerekana ubushobozi bwikigereranyo cyateye imbere cyo gusobanura itandukaniro ryamakuru yinganda, bityo bigatuma abantu benshi bagirira ikizere MFI ya MDPI;
